Living Proof Perfect hair Day (PhD) Heat Styling Spray 5.5 Oz

Living Proof Perfect hair Day (PhD) Heat Styling Spray is a heat protectant spray that does double duty by smoothing and shielding damp or dry hair from damage, with results that last up to 48 hours. Powered by Living Proof's patented Healthy Hair Molecule (OFPMA — Octafluoropentyl Methacrylate), it is the brand's proprietary solution for smoothness that protects from heat without weighing hair down or making it stiff or sticky. The formula delivers heat protection up to 450°F/230°C, making it compatible with blow dryers, flat irons, and curling tools alike. A sunflower-derived conditioning agent softens hair and increases manageability to control flyaways, a cationic polymer conditions and provides light hold, and a lightweight emollient blend smooths, enhances shine, and improves brushability. An ultra-fine aerosol mist applies evenly on damp or dry hair, ensuring full, consistent coverage from root to tip without product buildup. The formula is completely free of silicones, phthalates, and parabens, making it a clean-conscious choice safe for color-treated hair. PhD Heat Styling Spray works best on fine to medium hair types, though it can be layered with additional styling products for thicker or coarser strands. How to Use Hold the canister 6–10 inches away from damp or dry hair, section and apply in a sweeping motion throughout hair, then style with your preferred heat tool. Finish with a final spray for extra smoothness and shine. When applying to damp hair, combing through will help distribute the product evenly from root to tip. If static occurs during use, finish your look with an additional application to help lock in the style and add more smoothness and shine.
